Given Lift’s ability to convert food into investiture, if she took lerasiam could she eat something and convert it to the investiture she would need to use allomancy?

Hello, welcome to the Shard. Check out Sharder FAQ for some useful hints.

 

This seems unlikely. Metallic Arts are generally hard to fuel by external sources. Lift metabolizes food into Lifelight directly, which is keyed to Cultivation. This most likely will prevent her from using it to fuel Allomancy, if she were to have it. WoBs seems to all agree that it would take some extra work for Rosharan light to fuel Allomancy - just having it is not enough. I believe it would work if you were to unkey the light, just like unkeyed Dor can fuel other Invested Arts - but Lift has no means of unkeying her Lifelight. WoBs:

So you said that different Investitures from different worlds can fuel different Investitures, right? Would that mean that you could potentially use Stormlight for Allomancy and/or Feruchemy?

Brandon Sanderson

Yes, a little harder with the Metallic Arts [...]

Questioner

If I'm a Mistborn and I change planet-- if I go over to Roshar, do I have to bring metal from Scadrial with me?

Brandon Sanderson

No, you do not.

Questioner

Could I use Stormlight, and just have the same power?

Brandon Sanderson

Not-- not-- It would take some work.

Questioner

Yeah, okay. Okay, but I could use steel from Roshar, and you can-- Okay, thank you sir.

Questioner (paraphrased)

Can a Mistborn use the Investiture from a Highstorm?

Brandon Sanderson (paraphrased)

It takes some effort to convert the Investiture. They can burn metals from other planets, though.

Questioner

Is Investiture universal? By that I mean, if an Allomancer got Stormlight somehow could they use that to fuel Allomancy?

Brandon Sanderson

That is always possible, so yes.  But in some case it requires some quote-unquote hacking, like an AC vs a DC current or we've got a 120 Volt and they've got 240. Does that make sense? It might require-- I guess hacking is the wrong term, adapters.

If there's a Forger like Shai who plausibly had an opportunity to ingest lerasium and become Mistborn, but she passed it up, could she create a stamp that makes her temporarily a Mistborn?

Brandon Sanderson

She would have to have access to enough Investiture to make that happen. The stamp saying, "Hey, I'm a Mistborn!" doesn't actually give her the Investiture to do that. She could rewrite her past so that she took that bead. She would not actually be able to use the power, until she got an infusion of Investiture, which could be done with a stamp in the right manner, but most of the time you're gonna have to have some external source. Basically you're gonna have to take a hit of Investiture, a large amount of it, and then use the stamp, and then it will feed on that to change you into basically any of the other magics.

Stormlight?

Brandon Sanderson

If you could get a hit of Stormlight, that'd work. The problem is, Stormlight's not easy to get off of Roshar, and it still is technically keyed. You could get it a lot more easily-- Stormlight would work fairly well, but what you really want is some pure, unkeyed Dor. That stuff, you could do all kinds of things with. But, you know, it's kinda dangerous. But that's the stuff you're gonna want, or something like unto it.
